What is concealed penis?

Generally, concealed phimosis is a developmental anomaly of the male genitalia, characterized by a short-appearing penile shaft due to adhesion between the penile skin and the penile body, preventing normal exposure of the glans penis. The actual penile length is normal but is concealed beneath the prepubic fat pad or penile skin. Detailed analysis is as follows:

In most cases, it is caused by congenital developmental abnormalities, where the normal attachment between the penile skin and the penile body is absent, resulting in the penile shaft being enveloped. In some cases, acquired factors such as repeated infections of the penile area may lead to adhesion between the skin and the penile body. During urination, urine may accumulate within the foreskin, resulting in a weak urinary stream and ballooning of the foreskin. This condition may also impair normal penile development and increase the risk of urinary tract infections. After diagnosis, observation may be recommended during infancy, as symptoms may improve spontaneously with growth and development. If symptoms persist, treatment options include preputial dilation, which involves widening the foreskin opening with instruments to relieve the narrowing, or circumcision in severe cases, in which excess foreskin is removed to resolve the adhesions.

It is important to maintain cleanliness of the penile area in daily life, perform regular cleaning, and avoid infections. Parents should closely monitor their child's penile development and seek timely medical attention if abnormalities are noticed. Wearing loose-fitting clothing to reduce friction and pressure on the penile area is also recommended.
